Suddenly slow WiFi RBR850
Hi I’m having a weird issue, since i bought the RBS850 and RBS850 before 6 month they were working fine but suddenly since last week the WiFi speed dropped significantly from 500Mb to 180mb without ...
Same issue.
Cable modem service is consistently over 200Mbps.
Internet speed test from RBR850 consistently around 230Mbps.
Connections wired into LAN port are over 200Mbps.
All Wi-Fi connections are throttled to about 20Mbps.
Almost as if there is a configuration in the Orbi that is limiting throughput on WLAN.
Also, it’s very curious how the default 90 day support ran out just before this started to happen. Hmm… don’t pay for extended support and you get throttled?
What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?What devices are you speed testing with?

Firmware Version - V4.6.7.13_2.1.9
Comcast Internet using a Motorola MB7621 (DOCSIS 3.0)
- Bridge Mode. Not double NATed Router is getting public IP direct from Comcast.
Speed Test Results:
Mac directly to CM: ~230Mbps
RBR850 onboard speed test: ~230Mbps
Xbox X ethernet to satelite (RBS850) Wi-Fi 6e meshed to RBR850: ~230Mbps
Any Wi-Fi 2.4Ghz or 5gHz connection: ~20Mbps
- iPhones, iPads, Mac, Samsung S21, Windows PC with SpeedTest, Fast, Speakeasy, and Google across all platforms.
Note: FW was upgraded recently after slow throughput noticed. No improvement after upgrade.
I have professional experience with throttling technologies and this behavior matches to something artificially restricting Wi-Fi connections.
Has a factory reset and setup from scratch been performed since last FW update?
Is Armor enabled?
Try setting manual channel 1 and 40.
Set 40Mhz only and try changing CTS to 500 or 2347 Under Advanced Tab/Advanced Settings/Wireless Settings
